Thanks for your message: I have been monitoring ebay sites for a long time (US, France and Germany)
I know very well David M of Hunter Militaria: A very good merchant and he has created his business since February 2017.

I am not sure what he has in dups right now
he sells his dups no problem
some collectors hold out for trade
It seems when we look for certain
straps they are harder to find
I am looking for a K R 7 officers strap
with the number 7 and double underlay
yellow over white
